ANTENNA SIGNAL BOOSTER CIRCUIT - EXTERNAL



                                                               BC848
                                                                         FDN336P

The circuit is simple and need no coils.  It can be built on a general purpose PCB.  A vairable resistor is used to adjust the signal strength.  Use a volume control [linear type] in place, so that it can adjusted precisely according to the incoming RF signal.  [Click on image to Enlarge]
